INSTALLATION AND INSTRUCTION MANUAL

-1-
 These lights are NOT designed to replace the standard Turn Signals or Hazard lights on your vehicle.
 These lights are NOT designed to act as STOP or Brake lights.
 These lights, when activated via a user-supplied switch, will lash in a pre-programmed warning
pattern that is selected at the time o installation.
 I these lights are powered up, and a Turn Signal (blinker) is activated, the corresponding light will
mimic the lashing o the Turn Signal. The opposite light will either remain in the warning pattern
mode, deactivate (turn OFF), or become Steady Burn, depending upon initial programming o your
lights at the time o installation.
Functionality
 Installer must have irm knowledge o vehicle electrical systems & emergency equipment. It is the
sole responsibility of the installer to ensure the warning light is secure. The manufacturer
assumes no responsibility for the secure mounting of this light.
 I you need to drill any holes when installing this light, please take care to check that BOTH SIDES o
your drilling sur ace are clear rom obstructions.
 Use only soap and water when cleaning product. Use o other chemicals may discolor lens and/or
housing, diminishing light output. Replace discolored lenses immediately!
Installation Notes

Please Note: These instructions are provided as a general guideline only. Some
vehicles may require s ecial mounting, wiring, and/or weather-sealing. This is the
sole res onsibility of the installer. Star Headlight & Lantern Co., Inc. assumes no

IMPORTANT
3. Route the wires as
shown to the right:
4. Seal the wire hole with
silicone to prevent your
wires rom becoming
damaged.
5. If you are using the well nuts, push the
enclosed rubber well nuts through the
holes until the bottom side o the wider
lip rests on the sur ace o the vehicle.
6. Review the mounting diagram and use the appropriate screws to mount the bezel.
 Check the gasket to ensure it is resting flat and that there are no gaps
between the light and the mounting surface.
 Take extreme caution not to over tighten the screws!!! Over tightening
of the screws can stri the holes and result in a faulty mount.
7. Once the bezel is irmly attached to the mounting sur ace, seat the oam compression
gasket inside o it. Care ully eed any loose wire into the wire hole and press the LED
head into the bezel.
1. Use the gasket as a template
to mark your mounting holes.
2. Determine whether you are going to use the sel -tapping screws or the machine screws
and well nuts..
 Use the sel tapping screws or applications where the mounting sur ace is a minimum
o .060” (1/16”) thick and is composed o a material that will provide su icient “bite” or
the sel tapping screw.
 Use the machine screws and well nuts i your sur ace is less than .060” thick and/or
composed o a material insu icient or securing with sel tapping screws.

INSTALLATION

I you will be synchronizing two or more units together, leave the white wires disconnected until
programming for each has been completed. Connect the white wires rom the units together
ONLY AFTER PROGRAMMING them all or the same Pattern Type (Phase MAY di er).
Wiring
When wiring your lights, it is recommended that you take the ollowing
precautions to reduce any Electromagnetic Inter erence (EMI).
 Keep LED modules and any radios as ar away rom each other as possible.
 Separate the radio wires and the LED wires.
 Any excess wires should be cut short.
 The Ground wire, Power wire, and Synchronization wire should be bound tightly
together as they run rom light to light, through your switchbox, and to the battery.
 Do not ground each unit independently to the chassis. Run the ground or each unit
in a “bus” like structure, to the negative terminal on the battery.
Note: The total wire length between the two arthest units should be no more than 40 eet.

Programming
A ter the lights have been installed, and rior to connecting all of your wires, there are
several options you will need to decide upon and program.
The options MUST BE PROGRAMMED IN THE PROPER ORDER be ore use:
A. Single/S lit: Do you want your lights to operate in Single Mode or Split Mode?
B. O osite Light Function - When your lights are activated in Warning Mode and you
turn on your Turn Signal (blinker), what do you want the opposite light to do:
 Continue lashing in the pre-programmed warning pattern
 Turn o
 Become steady burn
C. Warning Light Pattern: What warning pattern do you want displayed when you
power up your DLHT lights?

A. S lit/Single Mode Programming
You will need to determine whether you wish to
run your light(s) in Split Mode or in Single Mode.
In Single Mode, the two halves o
the light will lash together
(simultaneous). This will give the
appearance o a "single" light,
rather than two halves.
In Split Mode, the two halves o
the light will lash opposite one
another (alternate).

Black - Ground
Red - Power
White - Power
Green - To program hold to Ground
Release Green After: Mode
Single Blink (at 3 sec) Single Mode
Double Blink (at 6 sec) Split Mode
(PROGRAMMING CONT'D)
3. A ter the light blinks once at 3 seconds, then twice at 6 seconds, release the Green wire,
wait one second, and disconnect the white wire rom power. The light should be in Split
Mode.
To change rom Split Mode to Single Mode, repeat steps 1 and 2, but instead release the
green wire rom Ground right a ter hal o the light blinks once at 3 seconds. This will place
the light back into Single Mode.
Please note that if you rogrammed your light as
described above, you MUST rogram the function of the
Non-Turn Signal head as described on the next age.
By de ault, the light comes preset or Single Mode. I Single mode is acceptable, please
skip to the B. Programming the Function of the Light O osite the Turn Signal section.
For Split Mode, proceed below:
1. Connect Black, Red, & White wires as listed to the below. Hal o the light will illuminate
into a steady burn and the other hal o the light will lash every three (3) seconds.
2. Touch and hold the Green wire to Ground.

B. O osite Light Function
When your lights are activated in Warning Mode and you turn on your Turn Signal (blinker),
the corresponding head will lash in conjunction with your turn signal. By de ault, the
opposite light will illuminate in a steady burn mode. I instead you would like the opposite
light to continue lashing in the pre-programmed warning pattern or turn OFF when the Turn
Signal is activated, proceed below:
Connect the Black, Red, and White wires as indicated below. When you hold the Green
wire to ground, the light will lash every 3 seconds. A ter 3 seconds it will blink once, a ter 6
seconds it will blink twice, a ter 9 seconds it will blink 3 times, and so on. Use the chart
below to determine the proper length to Hold the Green wire to program the desired mode.

Once the light lashes the appropriate number o times, remove the Green wire rom
Ground, then wait 1 second and remove the White wire rom power.

C. Warning Pattern Programming
Please note the ollowing points when programming the pattern:
 DO NOT CONNECT THE WHITE SYNCHRONIZATION WIRES TOGETHER UNTIL
EACH LIGHT HAS BEEN PROGRAMMED SEPARATELY!!!
 Each light has 10 di erent Pattern Ty es you can cycle through (A-J) in two
di erent Phases.
 I you will be synchronizing two heads (most applications), the two heads MUST be
programmed or the same Pattern Ty e.
 Lights programmed or the same Phase will lash the same, while lights programmed
or di erent Phases will lash opposite one another.
 I you are running in "Split Mode", the two halves will alternate the pattern back and
orth.
 For lights running in Split Mode, Patterns 1-10 lash side 1 in Phase 1 and side 2 in
Phase 2. Patterns 11-20 lash side 1 in Phase 2, and side 2 in Phase 1.
